etna.transforms.BinaryOperator#

class BinaryOperator(value)[source]#

Bases: str, Enum

Enum for mathematical operators from pandas.

Methods

perform(df, left_operand, right_operand, ...)

Perform binary operation on passed dataframe.

Attributes

perform(df: DataFrame, left_operand: str, right_operand: str, out_column: str) → DataFrame[source]#

Perform binary operation on passed dataframe.

If during the operation a division by zero of a positive number occurs, writes +inf to this cell of the column, if negative - -inf, if 0/0 - nan.
In the case of raising a negative number to a non-integer power, writes nan to this cell of the column.

Parameters:

df (DataFrame) – Source Dataframe
left_operand (str) – Name of the left column
right_operand (str) – Name of the right column
out_column (str) – Resulting column name, which contains the result of the operation operand(left, right)

Returns:
